I have a single phase, 220VAC 5hp motor that used to run but recently was moved and disconnected and lost name plate with the wiring diagram.There are six leads and I used an ohm meter to identify three coils, the starting coil attached to the three cylindrical caps. Can anyone tell me how to wire this together? I assume to reverse the direction I can swap the starting coil wires. Attached is a diagram of the configuration as found.

Usually these motors are dual voltage but this being 5 HP may be single voltage. It would draw too much current for 120 volt connection. Probably have to connect the two windings you have identified as 3-4 and 5-6 in series. However they must be connected with the correct polarity. Connect the start winding from what looks like 2-3 on your drawing to the center point of the main windings and to one of the outside legs. To reverse direction of rotation connect the start winding to the opposite outside leg. If it doesn't start it's likely that one of the mains is the wrong polarity. Reverse either main and try again. There should be a starting switch somewhere in that start circuit. The three items in the top of your drawing look like they are capacitors but no switch and they are not usually connected as shown. BTW, the number used here is not standard.

Maybe it's really a three phase motor that's been converted to single phase operation with a delta phase capacitor. I've seen them with several capacitors in parallel for start mode, with a switch to remove some for a run value.

I forgot to mention there is an easy way to check if you have the main windings connected correctly. Connect them in series and power up with 120 volts. Give the shaft a spin. You could wrap a string around the shaft and pull to get it spinning. The motor won't have much torque and will be slow starting. If the windings are not correct it won't run so reverse either winding and try again. Once that has been determined add the start winding.

All three caps are metal can, same size, but I can't read them without removing them.

I noticed that I numbered the leads to include two labeled "3". I will just call the second "3" now "7". So get that I need to wire the two running coils in series (connect leads 4 & 5, but after that I am not clear on your terminology:

"Connect the start winding from what looks like 2-3 on your drawing to the center point of the main windings and to one of the outside legs."

Are you calling leads "7" and "6" the outside legs? Is the center point leads "4" and "5"? When you say connect the start windings 2-3, to the center point, are saying connect lead "2" or "3" to 4-5? What happens to lead "1"?

Join 4-5. apply power to 3 and 6. Connect one end of the start winding, 3 to 4-5. Connect the remaining end (3) of the start winidng to either 3 or 6. If you conect to 3 it will rotate one direction, if you connect to 6 it will turn the opposite direction. (assuming 3-4 and 5-6 are the correct polarity. You may have to reverse 5-6).
